Boss health on right side of screen

Are the unit frames for bosses on the right side of the screen a part of the standard UI? I can't tell if they are blizzard, or DBM, neither seem to have settings for them. Trying to show them outside of a boss fight so I can move some other stuff out of the way.

Both the default Blizzard UI and DBM have boss health frames on the right side (though I believe DBM's are non-interactable). I'm not really sure the purpose of DBM's. In any case, you can hide/adjust DBM's health frames using the options GUI (in the "Health Frame" section). Also make sure "Show a boss health frame" isn't checked off for any boss in the actual raid module for whichever raid you're working on, if you don't ever want to see it.

That is not dead which can eternal lie.
And with strange aeons even death may die.
